xsl-fo:两个平行的报告，一个在奇数页，另一个在偶数页 [英] xsl-fo: Two reports en parallel, one in odd pages another in even pages

问题描述

我想生成一个 PDF，其中一个内容流在奇数页，另一个在偶数页，所以当你双面打印 PDF 时，你有一个模板来写笔记偶数页.这是我所拥有的，但它不起作用:

I want to generate a PDF having one content flow in odd pages and another in even pages, so when you print the PDF double sided you have a template to write notes even pages. This is what I have but it does not work:

    <?xml version="1.0" encoding="UTF-8"?> 
    <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
        <fo:layout-master-set>
            <!-- Odd Pages -->
            <fo:simple-page-master master-name="odd" page-height="297mm" page-width="210mm" margin-left="2mm" margin-right="2mm">
                <fo:region-body region-name="body-odd" margin-top="118mm" margin-bottom="50mm"/>
                <fo:region-before region-name="headerodd" extent="116mm"/>
                <fo:region-after region-name="footerodd" extent="48mm"/>
            </fo:simple-page-master>

            <!-- Even Pages -->
            <fo:simple-page-master master-name="even" page-height="297mm" page-width="210mm" margin-left="2mm" margin-right="2mm">
                <fo:region-body region-name="body-even" margin-top="118mm" margin-bottom="50mm"/>
                <fo:region-before region-name="headereven" extent="116mm"/>
                <fo:region-after region-name="footereven" extent="48mm"/>
            </fo:simple-page-master>

            <fo:page-sequence-master master-name="A4">
                <fo:repeatable-page-master-alternatives>
                    <fo:conditional-page-master-reference master-reference="odd" blank-or-not-blank="any" odd-or-even="odd"/>
                    <fo:conditional-page-master-reference master-reference="even" blank-or-not-blank="any" odd-or-even="even"/>
                </fo:repeatable-page-master-alternatives>
            </fo:page-sequence-master>
        </fo:layout-master-set>

        <fo:page-sequence master-reference="A4">
            <fo:flow flow-name="body-odd">
                <fo:block page-break-after="always">
                    This is an ODD page. Front-page report 1.
                </fo:block>
                <fo:block page-break-after="always">
                    This is an ODD page. Front-page report 1.
                </fo:block>
                <fo:block page-break-after="always">
                    This is an ODD page. Front-page report 1.
                </fo:block>
            </fo:flow>
        </fo:page-sequence>

        <fo:page-sequence master-reference="A4">
            <fo:flow flow-name="body-even">
                <fo:block page-break-after="always">
                    This is an EVEN page. Back-page report 2
                </fo:block>
                <fo:block page-break-after="always">
                    This is an EVEN page. Back-page report 2
                </fo:block>
                <fo:block page-break-after="always">
                    This is an EVEN page. Back-page report 2
                </fo:block>
            </fo:flow>
        </fo:page-sequence>

    </fo:root>

推荐答案

将笔记页面的静态内容放在指向 fo:region 的 fo:static-content 中-before(或任何其他外部区域)偶数页:

Put the static content for the notes pages in an fo:static-content that is directed to the fo:region-before (or any of the other outer regions) of the even page:

<fo:page-sequence master-reference="A4">
  <fo:static-content flow-name="headereven">
    <fo:block>
      This is an EVEN page. Back-page report 2
    </fo:block>
  </fo:static-content>
  <fo:flow flow-name="body-odd">
    <fo:block page-break-after="always">
      This is an ODD page. Front-page report 1.
    </fo:block>
    <fo:block page-break-after="always">
      This is an ODD page. Front-page report 1.
    </fo:block>
    <fo:block page-break-after="always">
      This is an ODD page. Front-page report 1.
    </fo:block>
  </fo:flow>
</fo:page-sequence>

这样，您就不需要拥有与您的真实内容相匹配的准确页数.

This way, you don't need to have exactly the right number of pages worth of note content to match your real content.

您可以定位内容，使其显示在页面上的正确位置.如果您将静态内容定向到 fo:region-before，则不必担心使用正确的范围，因为任何溢出该区域的内容在默认情况下都将保持可见.

You can position the content so that it shows up at the correct position on the page. If you direct the static content to fo:region-before, you shouldn't have to worry about using the correct extent since any content that overflows the region will remain visible by default.
